INTERNAL-COMBUSTION ENGINE.

' vcitizen of the United States, residing at Beloit, in the county Of Rock and State of Wisconsin," have invented a certain vnew Aand useful Improvement in Internal-Combustion Engines, of which the following is a specificatlon. l

My invention relates to internal combustion engines and more particularlyv the mechanism whereby the combustible gas or vapor is generated and supplied .to-the engine.

The object of the invention is to provide means whereby the engine may be made to both o-perate and start o n kerosene or oils somewhat heavier than kerosene.

I accomplish my Object by the mechanism illustrated in the accompanying drawings in which- Figure 1 is a perspective View of an engine equipped with my special apparatus. Fig; 2

is a detail showing in vertical section the Oil reservoir and associated parts. Fig. 3 is a section on the line 3 3, Fig. 2.

The engine is of the ordinary type in which a charge of air is drawn in by the piston, while at the Same time the suction charges this air with the necessary amount of liquid fuel vapor to ,form an explosive mixture. In the form selected to illustrate the invention the cylinder 1 is supplied with the explosive mixture through the intake 2.

This intake is connected with a cross 3 to which ordinary cold atmospheric air is Supplied through the nipple 4. Hot air is supplied through a pipe 5 which leads from a drum or jacket 6, open at some point to the atmosphere and surrounding the engineexhaust pipe 7. The hot gases issuing from the exhaust heat the air in said jacket and thus is furnished a constant supply of pure Warm air to the intake if desired. The pipes 4 and 5 are supplied with Suitable dampers 4 and 5 respectively whereby the flow to the intake may be regulated. Extending downward from the cross 3 is a pipe 10 closed at the lower end by a cap 11, these two parts forming a retort as will hereinafter ap ear.

(Sil is supplied to the retort through pipe 12 provided with a sight feed 13 leading from the oil reservoir 14. This latter is adapted to contain heavy oil such as kerosene or heavier oil and constructed in lany suitable manner for example, as shown in Specification of Letters Patent.

'Application kled April 20, 1912.y Serial No. 692,179.

.Patented sept. 15, 1914.-

Richardson Patent No. 690,610.- In the form here shown the reservoir has two com artments 14 and 14", one for containing lerosene and the other for containing water. The flow to the intake 2 is through ducts 14c and 14d respectively controlled by valves 14e and 14f .respectively.k The waterreservoir and its connectionsmay, however, be

omitted they form no partoi:l my present invention. The flow from pipe 12 and sight feed 13 is controlled by a spigot 15,*consequently oil can flow by gravity from the reservoir into the retort and be afterward shut oi' by the operator after the engine'has started running. A torch o-r burner 20' is located in position to heat the retort, said burnerI being supported in any suitable manner, for example, by bracket 21, secured to the retort.

Itwill be understood that the engine is to be both started and operated on heavy oil. Vith this in view, the reservoir will be filled with such oil preparatory to starting. lVhen ready to start, the attendant opens the spigot 15'and permits a limited amount of oil to gravitate into the retort 10. At the same time burner 20 is lighted and the flames thereof heat the retort to such a degree as to generate an explosive vapor. By preference, damper 5L will be opened at first and damper 4x1 closed so that the mixture supplied to the engine intake 2 will be warmed. The engine is thus supplied with a readily combustible mixture upon which it can start. After it has run long enough to get the parts well heated- Ithe spigot 15 can be turned oft', and the engine will run on the oil drawn direct from one of the compartments of the reser voir. The damper 4 may be left closed in order that the incoming fresh air may be heated, or it may be opened and the air partially or entirely supplied through the nipple 4. If cold air is wanted, damper 5n will be closed. By regulating thel openings of dempers 4 and 5 the proper ten'iperature may be obtained.

It will thus he seen that the engine is enabled to start vwith the same heavy oil upon which it ultimately runs, the attendant being able todivcrt part of the oil to the retort for starting and then stop the flow to the retort and permit the -oil to be taken direct from reservoir 14 into the intake 2. No additional movi ug parts are required with the exception of the valves, and the Astarting or vapor-generatin apparatus forms a constitutent parto the machine. v

Havingthus described my invention what I claim as new and desire to secureby Letters'Patent is: Y f

1, In an internal combustion engine the combination with the engine cylinder and in. take of areservoir adapted to supply heavy oil to said intake, a cross communicating with said intake, a retort communicating with said cross, a valved ductleading from said reservoir to said retort and two ductsd leading to said cross for su plying air thereto, one of said ducts leadling from the 'atmosphere and the other being adapted to supply heated air to said cross.

2. In an interna-l combustion engine the combination with the engine cylinder and in? take of a reservoir adapted to supply heavy oil to said intake, a retort, a valved duct leading from said reservoir to said retort, means for supplying air to said intake, and means for controlling the amount and the Y temperature'of the air admittedto said intake.

3. In an internal combustion engine the combination with the engine cylinder and intake of a reservoir adapted to supply heavy oil to said intake, a retort, a valved duct leading by gravity from said reservoir to said retort, a duct leading to said mtake from the atmosphere, a damper in said duct,

a drum open to the atmosphere and encircling the engine exhaust, a duct leading from said drum to said intake, and a dain-` per in the last mentioned duct.

4. In an internal combustion engine the combination with the engine cylinder and intake of a reservoir adapted to supply heavy oil to said intake, a-cross communicating with said intake, a pipe leading downward from said cross and having a closure at'the end, a valved duct leading by In witness whereof, I have hereunto subscribed my name-in the presence of two witnesses.
